Experimental details: Figure 1 Immunohistochemistry of SCC. Immunohistochemical staining for ASIC1, ASIC2, TRPV1 and TRPV4 in SCC tissue. ( a - d ) H&E staining, ( e - h ) immunohistochemical staining, inserted smaller pictures represent a two times larger perspective. Scale bars represent 200 mum. ( a - h ) Patient 8. This SCC shows no expression of ASIC2, only some peritumoral lymphocytes appear positive. The tumor cells show a weak, positive expression of TRPV1 and TRPV4. ASIC1 is expressed strongly on tumor cells. For more stainings of other SCCs, see Supplementary Figures S1-S3 .

( a - d ) H&E staining, ( e - h ) immunohistochemical staining, inserted smaller pictures give an overview. Scale bars represent 200 mum. ( a - h ) Patient 10. This BCC shows a strong expression of ASIC1 and TRPV1. The expression of TRPV4 is weak and positive, but this BCC shows no expression of ASIC2. For more stainings of other BCCs, see Supplementary Figures S4-S7 .

Experimental details: 1 FIGURE Immunohistochemistry of ASIC1/2 and TRPV1/4: (A) Representative samples of the most common skin tumors, that is basal cell carcinoma (BCC), squamous cell carcinoma (SCC), naevus cell naevus (NCN) and melanoma (MM) were stained for ASIC1, ASIC2, TRPV1 or TRPV4, according to the protocol as described in Nassios et al [ 36 ] and using the following primary antibodies: ASIC1: PA5-26778, ASIC2: PA5-26222, TRPV1: LS-B12677 (Thermo Fisher Scientific Inc, Waltham, MA, USA), TRPV4: ab21912 (abcam, Cambridge, UK). B, Normal skin (first row) and control tissues (second to fifth row) were stained for ASIC1, ASIC2, TRPV1 or TRPV4. Negative (second and third row) and positive (fourth and fifth row) controls were selected according to expression analyses published at the human protein atlas ( https://www.proteinatlas.org/ ). Scale bars: 100 um. Compared to epidermis, BCC showed strong expression of the four pH-sensitive proteins. In contrast, SCC showed a quite similar expression of all pH-sensitive proteins in comparison to normal epidermis, markedly weaker than BCC. For NCN and MM, epidermal and dermal expression was quite different. NCN exhibit strong expression of ASIC1/2 in the more superficial portion, while the intensity decreases in dermal melanocytes. However, TRPV1/4 seems to be uniformly expressed even in deeper tissue layers. In MM, ASIC1/2 and also TRPV1 are also expressed throughout the whole tumor. In contrast, TRPV4 staining showed only weak expression in MM, which
